@item -file_name_limit number
@kindex -file_name_limit curbs length of file names
@cindex File names, curb length, -file_name_limit
Set the maximum permissible length for file names in the range of 64 to 255.
Path components which are longer than the given number will get truncated
and have their last 33 bytes overwritten by a colon ':' and the
hex representation of the MD5 of the first 4095 bytes of the whole
oversized name. Potential incomplete UTF-8 characters will get their
leading bytes replaced by '_'.
@*
Linux kernels up to at least 4.1 misrepresent names of length 254 and 255.
If you expect such names in or under disk_paths and plan to mount the ISO
by such Linux kernels, consider to set -file_name_limit 253.
