glastree is a rather nice snapshot utility using hardlinks to reduce the space requirement. it is written in perl. a similar tool is pdumpfs, which is written in Ruby.
Created attachment 1883 [details] Changelog for glastree-0.57
Created attachment 1884 [details] glastree ebuild.
doh! the ebuild I uploaded misses the /usr in the INSTROOT, putting the package to /bin. sorry, again. *sigh*. I tested that it went in, but failed to notice the missing /usr. the correct src_install looks like: src_install () { make INSTROOT=${D}/usr install || die } sorry again, please don't hold this against glastree. ;-)
Checked in with modifications. Thank you for your contribution.
