Hello.
I am using the live-build version 20191221 (the one in testing) on a
debian stable/buster system.
Whenever I try to build an image (even the most basic with all the
default options) the live-build hangs trying to save the bootstrap stage
to cache with the following messages:
I: Base system installed successfully.
[2020-04-11 11:17:29] lb bootstrap_cache save
P: Saving bootstrap stage to cache...
cp: error reading 'chroot/proc/1/task/1/attr/prev': Ivalid argument
cp: error reading 'chroot/proc/1/task/1/attr/exec': Ivalid argument
cp: error reading 'chroot/proc/1/task/1/attr/fscreate': Ivalid
argument
cp: error reading 'chroot/proc/1/task/1/attr/keycreate': Ivalid
argument
cp: error reading 'chroot/proc/1/task/1/attr/sockcreate': Ivalid
argument
cp: error reading 'chroot/proc/1/task/1/mem': I/O error
cp: error reading 'chroot/proc/1/task/1/clear_refs': Ivalid argument
When this happens the ../cache/bootstrap/proc/1/task/1/pagemap file
starts to build up with garbage data until it runs my storage out of
space or until I stop the process with crtl+c.
I believe this is related to the saving of the bootstrap stage to cache
(besides the message saying so =P) because as soon I set the flag
--cache-stage deliberately stating to exclude this stage from caching
(with an empty value or defining other stages) the issue do not occur
and the build finishes without a problem.
This also happens in other machines running debian stable/buster with
this version of live-build and with the one in stable (20190311).
Can anyone help me diagnose this problem? The possibility to cache the
bootstrap stage would be very helpful for me :)
Thanks for your attention.
