fsck_ffs: Don't overrun mount device buffer
Maybe this case is impossible. Either way, when attempting to "/dev/"-prefix a
non-global device name, check that we do not overrun the f_mntfromname buffer.
In this case, truncating (with strlcpy or similar) would not be useful, since
the f_mntfromname result of getmntpt() is passed directly to open(2) later.

Fix buffer overrun in gcore(1) NT_PRPSINFO
Use size of destination buffer, rather than a constant that may or may not
correspond to the source buffer, to restrict the length of copied strings. In
particular, pr_fname has 16+1 characters but MAXCOMLEN is 18+1.
Use strlcpy instead of strncpy to ensure the result is nul-terminated. This
seems to be what is expected of these fields.

When rerooting, take the init(8) path from argv[0] instead of fetching

Kernel installs always override KMODDIR when installing modules, so
