Summary:
When you run 'eden start' without systemd integration, edenfs writes startup logs to the terminal to let users know that stuff is happening:
```
$ eden start
Starting edenfs (dev build), pid 2792025
Opening local RocksDB store...
Opened RocksDB store in 0.95 seconds.
Remounting 1 mount points...
Successfully remounted /data/users/strager/fbsource-dev
Started edenfs (pid 2792025)
Logs available at /data/users/strager/.eden-dev/logs/edenfs.log
```
These startup logs are also used by various tests (especially 'eden restart's tests).
Make the same thing happen when running 'eden start' with systemd integration, improving the user experience and making some tests work:
```
$ EDEN_EXPERIMENTAL_SYSTEMD=1 \
./buck-out/gen/eden/cli/eden.par start \
--daemon-binary "${PWD}/buck-out/gen/eden/fs/service/edenfs"
Starting edenfs (dev build), pid 2800760
Opening local RocksDB store...
Opened RocksDB store in 0.693 seconds.
Remounting 1 mount points...
Successfully remounted /data/users/strager/fbsource-dev
Started edenfs (pid 2800760)
```

# Some important escaping rules for how the quoted argument of 'sh -c' within
|
|
# ExecStart is interpreted by systemd:
|
|
#
|
|
# * '\' followed by a newline is replaced with ' ' (a space). (You *must* escape
|
|
# newlines with '\'.) A leading '\' escapes '\'. [1]
|
|
# * '\' followed by "'" (a single quote) is replaced with single quote. [2]
|
|
# * '$' followed by '$' is replaced with a single '$'. [3]
|
|
# * '%' followed by '%' is replaced with a single '%'. [4]
|
|
#
|
|
# Recommendations:
|
|
#
|
|
# * End each physical line with ' \' (a space followed by a backslash). [1]
|
|
# * Escape "'" (a single quote) using '\'. Use "can\'t", not "can't". Prefer
|
|
# using double quotes instead of single quotes. [2]
|
|
# * Escape '$' using '$'. Use '$${var}', not '$var' or '${var}'. [3]
|
|
# * Escape '%' using '%'. Use '100%% cool', not '100% cool'. [4]
|
|
# * Terminate commands with ';', if appropriate, instead of a newline. [5]
