Hi,
The following patch to /usr/src/release/Makefile allows the
specification of the variable FASTCLEAN, which instead of doing
a recursive rm on CHROOTDIR, simply umounts/newfs/mounts. Of
course, this is only useful if your CHROOTDIR location is a
separate mount point (which mine is: /snap).
Comments and critiques welcome.
Would someone consider committing this please?
Thanks,
John
