The page was written when systemd-repart was primarily intended to be used on a
running system. But nowadays it's more often used to create images, so extend
that part of the description.
While at it, fix some whitespace issues and trim some overly complicated sentences.
Certainly on systemd 252 at least a configuration of
```
MemorySwapMax=40%
```
is supported but this was missing from the man page.
Only MemoryMax was documented as supporting a %.
It's important if the binary specified by the init= boot option is not systemd
otherwise it confuses systemctl that incorrectly assumes that systemd is still
the init system due to the presence of /run/systemd/system.
Also some tools might also check the presence of /run/systemd/private to test
if systemd is running as pid1.
When building packages of arbitrary commits of systemd-stable,
distributors might want to include a git sha of the exact commit
they're on. Let's extend vcs-tag a little to make this possible.
If we're on a commit matching a tag, don't generate a git sha at all.
If we're not on a commit matching a tag, generate a vcs tag as usually.
However, if we're not in developer mode, don't append a '^' if the tree
is dirty to accomodate package builds applying various patches to the
tree which shouldn't be considered as "dirty" edits.
Let's rename the tool to tools/fetch-distro. It's useful to be able to fetch
the distro directly. But when that functionality is added, the old name is
confusing.
Now --update/-u must be specified to update the commits.
--reference-if-able is used to speed up the clone of debian.
It saves about 75% of the download.
If there is an error with the execv call in fork_agent the
program exits without any meaningful log message. Log the
command and errno so the user gets more information about
the failure.
Fixes: #33418

These tests identify a couple of problems with OPT pseudo-RR parsing.
First, any TTL value with the high bit set is replaced with zero before
checking the record type. For most types this is correct, since TTLs
have the range of signed int32. But for OPT records where the TTL is
repurposed to hold the extended RCODE, EDNS version and flags, it means
that the high bit cannot be used in extended RCODEs. Any RCODE with the
high bit set will be read as zero.
Second, the DNS_PACKET_RCODE() function bit-shifts the extended RCODE by
24 places instead of 20, so that it ends up forming the lower 8 bits of
a 12-bit RCODE, instead of the upper 8 bits as intended.
We intend to fix these issues in other pull requests.
