of [0,31] to files with no own data content. The new way is to have
a dedicated block to which all such files will point.
@*
"max_ce_entries="number sets the maximum number of SUSP CE entries and thus
continuation areas. Each continuation area can hold at most 2048 bytes of
SUSP data (Rock Ridge or AAIP). The first area can be smaller. There might
be some waste at the end of each area.
When the maximum number is exceeded during ISO filesystem production
then either xattr and ACL get dropped from the affected file or an error
gets reported and image production is prevented.
@*
Linux silently ignores a file when encountering its 32th CE entry.
(Workaround is to mount the filesystem with option "norock".)
So the default setting is 31. Minimum is 1, maximum is 100000.
If a limit higher than 31 is chosen and 31 gets surpassed, then a warning
message gets reported.
@*
"max_ce_drop="mode sets the behavior when the limit of max_ce_entries= is
surpassed. Mode "off" causes an error message and prevents image production.
Mode "xattr" and "xattr_acl" report a warning, delete from the affected
file all xattr of namespaces other than "isofs", and then try again.
If this still surpasses the limit, then mode "xattr_acl" deletes all ACL from
the file and retries.
If this still surpasses the limit, then an error message gets reported and
image production is prevented.
@*
Default setting is

Note: The term "ECMA-119 name" means the plain ISO 9660 names and attributes
which get visible if the reader ignores Rock Ridge.
