Support for xattrs, in TAR archives?

[vmlemon]

Thanks so much, for making ratarmount - it's solved a long-running need, in a really elegant manner. That said, are there any plans for supporting extended attributes, in TAR archives, since it'd make it easier, to work with files from Haiku, and MacOS, on Linux?

At least in the typical LIBARCHIVE/SCHILLY/BSDTAR-style format:

98 LIBARCHIVE.xattr.user.haiku.BEOS:TYPE#MIMS=YXBwbGljYXRpb24veC12bmQuaGFpa3Utc21iLXdvcmtncm91cAA
81 SCHILY.xattr.user.haiku.BEOS:TYPE#MIMS=application/x-vnd.haiku-smb-workgroup


Although IBM i/AIX, and Solaris seem to have PAX type-E records, of their own formats, and MPE/IX (example file, at https://www.openeloquence.com/support/B07/mpeclient2/tar.html) has records that look like, in "strings":

18 MPE.FILECODE=0
21 MPE.FILELIMIT=256
20 MPE.NUMEXTENTS=1
23 MPE.NUMUSERLABELS=0
22 MPE.BLOCKFACTOR=16
22 MPE.RECORDFORMAT=0
14 MPE.CCTL=0
15 MPE.ASCII=1
21 MPE.RECORDSIZE=80


I can provide example files, if it helps?

I'm glad ratarmount solved your need!

This seems like something that ratarmount should support in the future. Example files would be very welcome for testing!

This also seems to be relevant for the OCI format and the issue has interesting links for further reading.

No worries. borgbackup/borg#8479 has some IBM i, and Solaris ones, at least.
