Bugzilla Bug 121886

dev-db/firebird is the only ebuild using this flag, there are 5 other ebuilds
that use xinetd instead. 

# euse -i inetd
global use flags (searching: inetd)
************************************************************
no matching entries found

local use flags (searching: inetd)
************************************************************
[-    ] inetd (dev-db/firebird):
If you want inetd version instead of a superserver (daemon)

-------

# euse -i xinetd
global use flags (searching: xinetd)
************************************************************
no matching entries found

local use flags (searching: xinetd)
************************************************************
[+ C  ] xinetd (net-ftp/proftpd):
Enable support for starting from xinetd

[+ C  ] xinetd (net-ftp/vsftpd):
Add support for running under xinetd

[+ C  ] xinetd (net-mail/qpopper):
If you want inetd version instead of standalone

[+ C  ] xinetd (net-misc/linux-identd):
Use xinetd instead of the initscript

[+ C  ] xinetd (net-misc/rsync):
Install an xinetd.d file for rsyncd

Does firebird really need its own use flag for the same thing?

Fixed in portage, thanks for info.
