[$] LWN.net Weekly Edition for June 8, 2023
The LWN.net Weekly Edition for June 8, 2023 is
available.
[$] An introduction to EROFS
Gao Xiang gave an overview of the Extended Read-Only File
System (EROFS) in a filesystem session at the 2023 Linux Storage, Filesystem,
Memory-Management and BPF Summit. EROFS was added to Linux 5.4 in 2019 and
has been increasingly used in places beyond its roots as a filesystem for
Android and embedded devices.
Container images based on EROFS are being used
in many places these days, for example.
[$] A decision on composefs
At the end of our February article about the debate around
the composefs read-only, integrity-protected filesystem, it was predicted that
the topic would come up at the 2023 Linux Storage, Filesystem, Memory-Management
and BPF Summit. That happened on the second day of the summit when Alexander
Larsson led a session on composefs. While the mailing-list discussion was
somewhat contentious, the session was less so, since overlayfs can be made to
fit the needs of the composefs use cases. It turns out that an entirely new
filesystem is not really needed.
openSUSE Leap 15.5 released
Version 15.5 of the openSUSE Leap distribution has been
released. This is not intended as a feature release, but brings updated
versions of many packages. The project has also announced that there will be
one more 15.x release before that series ends and users have to migrate to
whatever its successor will be.
Security updates for Wednesday
Security updates have been issued by Debian (c-ares),
Fedora (curl and firefox), Oracle (cups-filters, kernel, and webkit2gtk3), Red
Hat (emacs and kpatch-patch), Slackware (mozilla), SUSE (kernel and openssl-
1_0_0), and Ubuntu (firefox and libreoffice).
