Manual instructions are from 2020, we gained /etc/login.d/* support
in 2022, so automate it.

(I have no idea if/how i2pd actually works.)

Feedback? OK?

 Resource Limits: File Descriptors
 =================================
 
-By default, the i2pd process runs in the login(1) class of "daemon".
-The default limits on file descriptors are insufficient to run i2pd; instead you
-should put the _i2pd user and process in their own login(1) class with tuned
-resources.
-You should also raise the system-wide maxfiles limit.
-
-1. Configure i2pd login class in the login.conf(5) file:
-
-        i2pd:\
-                :openfiles-cur=8192:\
-                :openfiles-max=8192:\
-                :tc=daemon:
-
-2. Adjust kern.maxfiles, if needed:
+You should raise the system-wide maxfiles limit:
 
 	# sysctl kern.maxfiles=16000
 	# echo "kern.maxfiles=16000" >> /etc/sysctl.conf
