Description Colin Walters 2014-05-16 09:04:06 UTC

For rpm-ostree, I am using dracut on a compose server side - clients merely replicate the pregenerated images.

The problem is that right now I am rebuilding the initramfs any time any package changes, because I don't know what dracut is going to put in there.

What I'd like is something like:

dracut --print-dependencies

I could then resolve this to RPMs, and resolve their dependencies.  If the input to dracut hasn't changed, I could then just reuse the previously generated initramfs.

BTW, we could also use this on the client side instead of just relying on kernel %post - it's conceptually broken that the only time we generate the initramfs is on kernel install.  You can get an old version of systemd in the initramfs for a while until the kernel is updated.

Comment 1 Colin Walters 2014-09-09 19:04:16 UTC

Also, note this whole model reverts the dracut hostonly change.  What we need to do instead is ensure that the OS works with an immutable initramfs, and any additional configuration state (such as keyboard mappings, systemd machine id) are stored as kernel commandline arguments, or as concatenated initramfs images.

Comment 2 Harald Hoyer 2014-09-10 09:21:40 UTC

I agree, that such a feature would be nice.

That might be dangerous, because on kernel updates, you will at least have a fallback entry in the bootloader for an older initramfs.

Comment 7 Fedora End Of Life 2016-07-19 11:31:51 UTC

Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
