| 2024-02-20 | syscalls: ‘processes’ really omits kernel threads....Fixes a bug whereby ‘processes’ would include kernel threads, thereby
leading the ‘stop’ method of ‘user-processes’ to wait indefinitely for a
kernel thread. Code taken from the Shepherd.
Fixes <https://issues.guix.gnu.org/68800>.
* guix/build/syscalls.scm (kernel?): Remove.
(linux-process-flags, linux-kernel-thread?, pseudo-process?): New
procedures.
(PF_KTHREAD): New variable.
(processes): Use ‘pseudo-process?’ instead of ‘kernel?’.

| 2023-11-25 | syscalls: Add fallback case for ‘terminal-string-width’....This makes ‘terminal-string-width’ synonymous with ‘string-length’ when
running one a statically-linked Guile, as is the case in some unit
tests, instead of throwing ENOSYS.
* guix/build/syscalls.scm (terminal-string-width): Use ‘dynamic-func’
and ‘pointer->procedure’ instead of ‘syscall->procedure’. Return
‘string-length’ when one of the ‘dynamic-func’ calls fails.

| 2023-10-23 | syscalls: Add support for musl libc....This commit allows using Guix on a foreign distro which uses musl libc,
for example, Alpine Linux. Usage of musl libc is detected via a new
musl-libc? variable using the Guile %host-type.
Using the new musl-libc? variable, we can now implement musl-specific
quirks. The two compatibility problems I encountered in this regard are
that musl dose not export a readdir64 and statfs64 symbol. On musl,
these two functions are implemented as CPP macros that expand to
readdir/statfs. To workaround that, a case-distinction was added.
The existing linux? variable has been modified to return true if the
%host-system contains "linux-" in order to ensure it is true for both
linux-gnu as well as linux-musl host systems.
The patch has been tested on Alpine Linux and is already used for the
downstream Guix package shipped in Alpine Linux's package repository.
* guix/build/syscalls.scm (musl-libc?): New variable.
(linux?): Truth value on any linux system.
(statfs, readdir-procedure): Support musl libc.

| 2021-03-15 | syscalls: mounts: Fix a matching bug....On some systems, the columns in /proc/self/mountinfo look like this:
23 28 0:21 / /proc rw,nosuid,nodev,noexec,relatime shared:11 - proc proc rw
Before this change, the mounts procedure was written with the assumption that
the type and source could always be found in columns 8 and 9, respectively.
However, the proc(5) man page explains that there can be zero or more optional
fields starting at column 7 (e.g., "shared:11" above), so this assumption is
false in some situations.
* guix/build/syscalls.scm (mounts): Update the match pattern to use ellipsis
to match zero or more optional fields followed by a single hyphen. Remove the
trailing ellipsis, since multiple ellipses are not allowed in the same level.
The proc(5) man page indicates that there are no additional columns, so it is
probably OK to match an exact number of columns at the end like this.

Previously, we'd choose at expansion time whether to use the Hurd or the
