bug#54483: ‘guix system image’ chokes on host's /var

[Tobias Geerinckx-Rice via Bug reports for GNU Guix]

Guix,

I can't build the older installer image I want, ostensibly because my 
installed system is too new (anno-post-apteryx-versioning; no time to 
further investigate I'm afraid).

I expect a self-contained system not to care and certainly not to crash.

For a nicer backtrace, could you run "make" before "./pre-inst-env",
such that file name and line number information would be present in
the backtrace instead of all the (ice-9 eval)?

Greetings,
Maxime.

Also, COLUMNS=900 can be useful to avoid truncation.

The ugly backtrace is gone with
47960b55268220ca1cb7d2fed41c53873181d816.

However, fundamentally, ‘guix system image’ shouldn’t be reading
/run/current-system/parameters because it has not use for it.

Mathieu, do you happen to have an idea where to remove that
‘read-boot-parameters-file’ call?  :-)

Thanks,
Ludo’.

Yes, that's because profile-boot-parameters was always evaluated in the
perform-action procedure of the (guix scripts system) module.

This has recently been fixed with
9d30cfa3372cccc847e75038d34c4ea5b8d8b241. Tobias, you can cherry-pick
this patch on top of 1.3.0 if you'd like to generate an old installer
image. I just managed to do so successfully :).

Closing this one,

Thanks,

Mathieu
