The option says "Ext2fs extended attributes support".
Very little need this out of the box, but need to pull yet another port into the system. For those who need this can enable with make config, but 99% don't need it.
Please disable this by default to reduce dependencies.

Yeah, the description is a bit misleading, it's not limited exclusively to ext2fs, but can also manage UFS-specific flags like append-only, etc.

Given that there are other issues* with it, I guess it makes sense to disable it by default.
(In reply to Alexey Dokuchaev from comment #1)
Hah, I have exactly the same problem as Oleg, but did not notice because I am on thick jails. Yet another reason to disable it.

misc/mc: the port had been improved (+)
- By popular demand, disable EXTATTR option by default: the benefits
it provides are outweighed by having to pull `sysutils/e2fsprogs'
port as dependency and various troubles people are having with it.
While here, adjust the description as it was is a bit misleading:
it is not limited exclusively to ext2fs, but can also manage UFS-
specific flags like append-only, etc. 
- Fix ZIP/UNZIP program detection and add missing dependency on the
`archivers/zip' as FreeBSD does not provide native zip(1) program.
This bug had been present since late 2014: when fixing PR 193766,
an incomplete patch had been committed; it went unnoticed because
apparently users rarely create ZIP archives, and extraction worked
because `archivers/unzip' is very commonly installed package
