| Subject: | [opensuse] Manual dist upgrade procedure(s) & tools/progs/aids? |
| Group: | Suse-linux-e |
| From: | Linda Walsh |
| Date: | 5 May 2008 |
the "official" upgrade procedure: booting from the new media boot-disk
and having all packages updated at one time while the system is
"offline" (not usable for other tasks).
This isn't necessary a trivial or officially supported or sanctioned way
to do things, but I have my reasons for doing things this way...
When I say "utility" that can help me do this, I mean utility as being
one of (or a combination of) a "program", "script", "collection of
scripts".
I want to upgrade a 'live' system, that was based on an older suse
release (suse9.3 in this case) to newer packages -- mostly from 10.3 (or
10.2 for packages that are broken in 10.3). Theoretically, (or
ideally), the utility would work with any RPM based distribution, but my
main focus is on SuSE's dists right now (as has been case for ... since
~ suse 6.x or 7.x).
So -- want to have a util that can inspect my current RPM's, and pick
out the updates from the target dist (in this case 10.3), find the
needed deps and install them.
I want the command to be able to be run over some "set" of older RPM's
at 1 time.
I'm doing this logged in *remotely* (not at a console), so amusing ssh
-- so an example of doing things partially -- would be to upgrade
"open-ssh" and its requirements 1st, then install and get it working
before continuing (ensuring that remote access will continue to work
through the remainder of the upgrade). In my current situation, that's
already done.
But what gets to be hairy is, making sure mutually dependent RPM's are
updated in 1 rpm command so all their reqs & obsoletes are handled in
the same command so the system doesn't (ideally) need to transition to a
"bad-state" where something is broken.
Are there any tools to help me upgrade a package (with the new RPM's
being *local* (either on same machine, or on a local subnet available
via "whatever" (SMB, NFS, scp/ssh), that would solve (resolve) package
dependencies, conflicts and obsoletes and generate or execute a single
rpm command, "at a time", that would consistent within itself?
I don't want it to upgrade *all* RPM's at one time -- just the
necessary, dependent ones.
There are two types of RPMs that need to be upgraded:
1) those RPMs that either a) have no prereqs, or b) already have all
needed pre-reqs installed
2) those RPM's that need other RPM packages to be updated at the same
time in order to solve dependencies
Is there command-line utility (prog, script, set of scripts) that does
this already?
Is this a utility other "manual-updater" hacker-types would find useful
or helpful?
-------
Right now, I have to go through all of this process manually (which is a
bit labor intensive), but I'd like to have a util (or set of utils) that
could find needed pre-reqs so I could execute 1 RPM command at a time
that would upgrade some interdependent "subset" of packages.
So does such exist? Does anyone else go through manual upgrading
because they maybe:
1) aren't on the same-update cycle frequency as new
distribution-versions are released?
and/or
2) Don't want to bring down the active system they are updating except
for simple 'reboots' when needed (like to activate a new running
kernel)?
and/or
3) only want to upgrade *select* newer packages that "need to be
updated" (for whatever reason, bugs, features, etc.).
---
Maybe there is a utility, perhaps built on top of rpm, that already does
most of this? A preliminary look at "yum" didn't seem to show it was
what I wanted and its workings were a bit cryptic. I tried it, but
my early attempts shed no light on how 'yum' might provide these
features. I tried:
> yum check-update localupdate this gave the output:
primary.xml.gz 100% |=========================| 7.8 MB 00:26
opensuse : ################################################## 17136/17136
opensuse-updates 100% |=========================| 1.2 kB 00:00
primary.xml.gz 100% |=========================| 1.7 MB 00:08
opensuse-u: ################################################## 4584/4584
--- This didn't really tell me what it did or what it was trying to do.
It didn't appear to do any upgrading of existing older packages, so I'm
not sure what it did.
I tried adding the '-v'erbose switch, and repeating the command, but
that only generated more questions about what it was doing. Partial
output:
Installroot: /
Ext Commands:
localupdate
Reading Local RPMDB
Setting up Package Sacks
Building updates object
putting libzypp in complex update
putting libevent in simple update
putting ghostscript-x11 in complex update
putting wv in simple update
.... [ continues with "putting <pkg> in [simple|complexe] update"]
(about 160 pkgs total, then: )
processing libzypp
processing ghostscript-x11
.... [ Continues processing *only( 'complex' packages from above ]
Matching packages for package list to user args
( Program exits w/status 0)
So it doesn't seem to be what I want (that's ok, just wondered if it
was going to try to do what I wanted, but it seems it's for a different
purpose).
Haven't tried any other tools at this point. Ideas?
Anyone else interested in this subject? Is there a better place to
find people who might be interested or know about such tools?
Thanks much,
Linda W.
