[Bug 863886] [NEW] compcache is not working if COMPCACHE_SIZE contains whitespaces

[Eugene San]

Public bug reported:

Since initramfs-tools-0.99ubuntu5 is working out of the box, but:
compcache is not working if COMPCACHE_SIZE, in /etc/initramfs-tools/initramfs.conf contains whitespaces.
While instructions in same file instructs to do exactly that.

Elimination whitespaces solves the problem.
I recommend updating as following:
