update-kernel: does not update successfully on Pi / diskless
Just tried to update kernel on a 3.17 PiZero in diskless setup (ref #10470 (closed)).
(release is on kernel 5.15.79, linux-rpi 5.15.81 is available in main)
All seems to work fine, until:
umount: can't unmount /.modloop: Resource busy
no other errors reported.
In the end produced files do not land in /media/mmcblk0p1/boot
which remains with original files: produced files are not copied-over...
No report of failing copies either.
Was executed as root
, with TMPDIR="/media/spare/SPARE" update-kernel
, and /media/mmcblk0p1
was remounted rw
before (just in case script under-looks it).
Thoughts?
