Freebsd unremoveable directories
When I was trying to get my FreeBSD working as a XenU, I used the make option DESTDIR= for installworld and installkernel.
After the files had been installed in my DESTDIR directory however, I wasn’t able to remove certain directories when I tried to remove my DESTDIR for a clean new install:

After getting really annoyed with all the directories piling up in my /usr/local/xen directory, Benv offered to try and find out why the hell these directories didn’t want to get deleted.
It seemed that the directories had a flag ’schg’ which you can see by doing an ‘ls -lo’ on the directory. The ’schg’ flag means that the directory is system immutable and only the owner and superuser are allowed to remove this flag.
This is done by calling chflags 0 on the directory. This clears all it’s flags.
I fixed my problem by doing:
find . -exec chflags 0 "{}" \;
rm -rf /usr/local/xen/current-root
