No... actually upstream targetcli/rtslib are not very well maintained.
Around 5 patches each in the last year.

Meanwhile, I have been actively maintaining branches at
github.com/agrover/targetcli-fb and github.com/agrover/rtslib-fb. We
have a man page and screencasts even. Feel free to file bugs against
them and I'll respond.

But I'm only packaging for Fedora/RHEL, so random people on Debian etc.
get a bad experience. I'd like to see upstream accept my AGPLv3-licensed
patches, or have Debian package the -fb versions, either instead or in
addition to the upstream versions.

(I'd kinda been waiting to bring it up until upstream had no commits in
a year, but since you mentioned it...)
