+Since embedded systems usually avoid writing continously on non-volatile storage
|
|
|
+(to avoid waer-out of the storage device) there are no logfiles under /var/log and
|
|
|
+/var itself is mapped onto a RAM based filesystem.
|
|
|
+
|
|
|
+Instead the syslog daemon logs into a ciruclar memory
|
|
|
+buffer. The size of the memory buffer is by default 32KiB and can be changed in the
|
|
|
+busybox configuration.
|
|
|

|
|
|
+To access the content of the buffer the +logread+ utility is used to dump the buffer.
|
|
|
+To get a continous output of the logbuffer -f has to be added as option.

+-f Output data as log grows

+-F Same as -f, but dump buffer first
