i'm reading some documentation that claims that neither ext3 device
files nor symlinks cost you any data blocks in the filesystem. sure,
that's obvious with device files, but symlinks?
i always thought that symlinks cost you a single data block -- just
enough to store the actual character value of the file being linked
to. the only way i could see that not being true was if the ext3
inode allocated some space internally to hold that information for
suitably short filenames, but i've perused the ext3_inode structure in
include/linux/ext3_fs.h and i don't see that unless i'm just missing
it.
thoughts? can anyone clarify this? thanks.
