Cannot make a chroot, build, etc.

[Simon Glass]

Hi,

I hit problems where I cannot produce working binaries, so decided to try removing my chroot.

I'm sure I missed a PSA somewhere, since I seem to be the only one with problems. Any pointers please?

Regards,

Simon

does your system have a /dev/shm ?

This problem occurs when your mount cache is out of date. One
workaround is to rename your build directory or reboot the machine.

The real fix is to update enter_chroot.sh to use /proc/mounts instead of
mount. Something like this: http://pastebin.com/EQ62iAWX

David Hendrix ran into the same problem and the above change fixed it locally.

Cheers,

David

i'm not sure that's entirely safe ... the "on" match was helping
anchor to the 3rd position in the mount output. we'll have to tweak
the match slightly to make it work with /proc/mounts.

maybe something like:
MOUNT_CACHE=$(awk '{print $2}' /proc/mounts)

and then:
case " ${MOUNT_CACHE} " in
*" ${mounted_path} "*)
# Already mounted!
;;

i'll post a CL for it

That code needs to be moved out of crosutils and into cros_sdk anyways (I've been agitating for that for a while).

Any takers?
