i currently use the output of sha512sum in several places of xbmk, which is a bit unreliable in case output changes. other cases where i use util outputs in variables are probably reliable, because i'm using mostly posix utilities in those. to mitigate this, i now import suckless sbase, which has a reasonable sha512sum implementation. *every* binary it builds is being placed in build.list, because i'll probably start using more of them. for example, i may start modifying the "date" implementation, adding the GNU-specific options that i need as mentioned on init.sh i'm importing it in util/ because the sha512sum util is needed for verifying project sources, so if sbase itself is a "project source", that means we can into a chicken and egg bootstrapping problem. this is sbase at revision: 055cc1ae1b3a13c3d8f25af0a4a3316590efcd48 Signed-off-by: Leah Rowe <leah@libreboot.org>
